[0014] Figure 3 is Figure 1 a schematic structural diagram of the rotating shaft shown.

[0015] In the figure: annular mounting base 1, rotating shaft 2, water sample bottle 3, sampling tube 4, first liquid detection and sensing device 5, second liquid detection and sensing device 6, mounting position 7, connection port 8, first telescopic rod 9, second telescopic rod 10. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] The present invention will be further described in detail below with reference to the accompanying drawings.

[0017] As Figure 1 shown, the liquid monitoring and compensation device of the automatic sampler mainly includes an annular mounting base 1 and a rotating shaft 2. Among them, the rotating shaft 2 is vertically arranged and located at the center of the ring of the annular mounting base 1.

[0018] As Figure 2 shown, a plurality of mounting positions 7 are provided around the annular mounting base 1, and a plurality of water sample bottles 3 can be installed on each mounting position 7 as required. Among them, under the operation of a peristaltic pump, the water sample can be pumped into each water sample bottle 3.

[0019] The top opening of the water sample bottle 3 is transparent and open at the top, and the water sample therein can be detected from the top and the side respectively.

[0020] As Figure 3 shown, the top of the rotating shaft 2 has a connection port 8, and the connection port 8 is connected to a power device such as a motor. Under the operation of the power device, the rotating shaft 2 and each structure thereon can rotate.

[0021] A sampling tube 4 extends from the upper side surface of the rotating shaft 2. The end of the sampling tube 4 is bent vertically, and its end port faces downward and is directly above one of the water sample bottles 3 on the annular mounting base 1. A first liquid detection sensing device 5 is installed on the sampling tube 4, and the first liquid detection sensing device 5 can detect whether there is water in the water sample bottle 3.

[0022] A second liquid detection sensing device 6 is installed on the bottom side surface of the rotating shaft 2, and the second liquid detection sensing device 6 faces the outer side surface of one of the water sample bottles 3. Among them, the bottom of the rotating shaft 2 is connected to a vertically extending first telescopic rod 9. The bottom end of the first telescopic rod 9 is connected to a horizontally extending second telescopic rod 10, and the second liquid detection sensing device 6 is installed at the end of the second telescopic rod 10. Thus, the second liquid detection sensing device 6 can detect the water level in the corresponding water sample bottle 3. The first telescopic rod 9 can be operated to extend and retract to adjust the height of the second liquid detection sensing device 6 to the height where sampling should be performed. The second telescopic rod 10 can be operated to extend and retract to adjust the distance between the second liquid detection sensing device 6 and the water sample bottle 3, so as to be applicable to water sample bottles 3 of different sizes.

[0023] Preferably, scales are provided on the first telescopic rod 9, which can more accurately adjust the height of the second liquid detection sensing device 6.

[0024] When using this automatic sampler liquid monitoring compensation device, the peristaltic pump operates to collect water samples and introduce them into each water sample bottle 3. At the same time, the power device operates to rotate the rotating shaft 2 and drive the first liquid detection sensing device 5 and the second liquid detection sensing device 6 to move accordingly. Then, the first liquid detection sensing device 5 can be used to detect each water sample bottle 3 from above first. If no signal indicating the presence of water is detected in a certain water sample bottle 3, it means that effective sampling has not been performed at this sampling point or there is a malfunction in the sampling device, etc. When the first liquid detection sensing device 5 normally detects the water in each water sample bottle 3, the second liquid detection sensing device 6 is then used to detect the water level in each water sample bottle 3 from a certain side position. If no signal indicating that the water has reached the corresponding water level is detected in a certain water sample bottle 3, it means that the collected water sample does not meet the current set requirements, or there is an abnormality such as a blockage in the sampling tube 4 path.

[0025] An automatic sampler liquid monitoring compensation device in the present utility model mainly has the following beneficial effects:

[0026] 1. It can track liquids in real time, evaluate the actual operating conditions of the sampler, and improve the management level of the sampler;

[0027] 2. It can monitor and evaluate the actual operating conditions of the collector's collection situation and sample collection situation in real time in various sampling environments;

[0028] 3. It can monitor the real-time sampling process of the sampler quickly, accurately and reliably, detect abnormal problems in time, ensure the data accuracy of water sample detection and analysis, and is conducive to the analysis of water body substances;

[0029] 4. Novel in structure, simple and compact, portable to install, good in stability, and can ensure the extraction of the water sample bottle 3 and the liquid detection accuracy.

[0030] The above are only some embodiments of the present utility model. For those of ordinary skill in the art, without departing from the inventive concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model.
